Don't think it's crazy at all... One of the guys over in the RPi land managed to get Chromeum built on the RPi (although I don't know if he ever managed to finish it) and that has 1/4 the performance and 1/2 the RAM to work with...
What kind of images for other software do I need. For instance Kali Linux Which Image do I Use ARMHF ARMEL RASPBERRY PI I386 IMAGE. Thanks.
